PEDAL RUBBER.

Application filed August 2%, 1919.

To @ZZ whom if may concern:

Be it known that I, ltoscon S. lilnrsno a citizen of the United States, residing at Middletown, in the county of Butler 'and State or Ohio, have invented a new and useful Im provenient in Pedal Rubbers, of which the Jfollowing is a specification,

This application relates to pedal rubbers and is particularly adapted to be used on bicycles. i

lt is very desirable to make that part ot' a bicycle pedal on which the foot bears of rubber and to mount it in the pedal on a bolt passing longitudinally through a hole therein. Heretofore, however, it has been found very diflicult to make a satisfactory pedal rubber for the reason that the bolt had a tendency to out its way through the rubber,

ausing the part to be lost or thrown away long before it was otherwise worn out.

My invention which overcomes this objection is fully described in the following specification and shown in the drawing in which,

Figure l is an elevation of a pedal showing` one of my pedal rubbers in section;

Fig. 2 is an elevation of apedal rubber with the rubber partly broken away; and

Fig. 3 is a section on the line of F ig. 2.

l have embodied my invention in a bicycle pedal l0 having end plates il and l2 which may be mounted in any desired manner to rotate about a spindle 13 which is screwed into a pedal crank 14. rEllis pedal has bolts l5 connecting' the end plates l1 and l2 and passing through longitudinal holes 16 in pedal rubbers 16. n

My pedal rubber diers from the ordinary construction by having a metal reinforced longitudinal hole. rThis reinforcement is Specification of Letters Patent.

preferably in the form of a helical spring or sleeve l? formed of a Hat steel strip which is wound on a mandrel in long lengths and out to the length desired t'or use in the pedal rubber.

These springs are then placed on cores in a mould and the mould illed with an unvulcanized rubber mixture which is forced intimately around the spring. Heat is then applied and the rubber is vulcanized in any well known manner. The rubber thus strongly adheres to the spring and as the pressure or' the foot is applied to the pedal, neither the spring nor the bolt therein can cut its way through the rubber.

W'hile l have shown and described but a single embodiment of my invention, it is to be understood that it is capable or many modifications. Changes therefore in the construction and arrangement may `be made without departing from the spirit and scope ol the invention as disclosed in the appended claims.

lV hat l claim as new and desire to secure by Letters Patent is:

l. The combination of a bicycle pedal rubber having a central longitudinal opening therethrough 'for the supporting rod thereof, with a spiral wire sleeve surrounding said opening and contacting with and f0rming a bearing for the pedal rod, substantially as set forth.

2. The combination ot' a bicycle pedal rubber having a central longitudinal opening therethrough for the supporting rod thereof, with a spiral wire sleeve surrounding said opening and vulcanized in said rubber and contacting with and forming a bearing for the pedal rod, substantially as set forth.
